Lack of stimulation pleasure? I don't feel any pleasure when I do anything down there

I have a question about sexual stimulation. I'm quite young and adventurous and have tried masturbation. When I try to do anything 'down there' it feels off. I can feel it, but it's not like what everyone describes it as. For example, If I press on any part down there, it just feels like it would if I pressed on my wrist or my hand. I just want to know if something is wrong. I've not really brought up any answers about it and I honestly have concerns because I can't find anything like it on the internet.
